My 3-year-old lime tree has suddenly produced a crop of limes that are brownish gray on the upper sides. The entire tree is covered with these limes. What is this? What can I do to return the tree to its previous fecundity?

Limes that are mostly brownish in color should be avoided since this may be an indication that they have "scald", which may cause them to have an undesirable moldy taste. Scald is usually caused by freezing or sunscald in winter. Wrapping the trees during this time, or bringing potted plants inside, will often alleviate this problem.
